If the hand controller on the LX6 has stopped working you have a problem since meade does not support this very old telescope. My only suggestion would be to place an ad on www.astromart.com looking for a new hand controller.

If the error message indicates a "motor fault" make sure you have a good power supply and or fresh batteries-- as low voltage will cause a motor fault error.

Later you said it was an LX90 LNT-- ?? so which scope do you actually own???

RESET the hand controller and then re-enter, Time, Date, and Site, and Standard Time.

After the above do another alignment.

If nothing -- then reload the hand controller firmware.

You may have Corrupted firmware in the hand controller- that's why they want you to do a RESET.

You might have to reload the correct firmware to fix this problem.

I believe if you hold down the ENTER KEY and the SCROLL DOWN arrow key and then turn on the scope you enter SAFE LOAD where you can reload the firmware.

Meade 14'' LX 200 GPS telescope


If it will not boot-up it's probably the main board. However, I would try a brand new hand controller cable first before I panic.

A fellow by the name of Ron Sampson can repair the hand controller and or the main board circuits. He can be contacted by placing a message for him on the LX200 and the LX90 Yahoo Tech Group.

Hope that helps you. You can send him the hand controller and the main board and he will have a look at it.

Meade 10" LX6: I need to find what color wires connect to what pins in the Encoder Junction Box connector. Appears that several may be broken and I don't have a schematic. Does anyone have the schematic...


This is a very old LX6 telescope. I have never seen a schematic on the internet. Except for these articles:
http://www.astromag.co.uk/pdfs/lx6.pdf

This person may be able to help you:
http://www.onealwebsite.com/AstroPage/Telescopes.html

and this on page 33-34
http://skywatch.brainiac.com/used/used_sct.pdf

You can also call Meade directly and see if they have one:
http://www.meade.com/support/index.html

Finally, you can post a message on the Yahoo LX90 and LX200 group and ask for help from either Dr. Clay, or Ron Sampson. Both of these folks repair Meade brand telescopes.

This is a very old Meade SCT telescope. You can try contacting Meade customer service but I would doubt that they still have parts??

http://www.meade.com/support/index.html

So, go to the Yahoo Groups LX200 forum and join and ask questions. Someone may have that model Meade SCT. Also there are people on the forum that can repair the circuits in the hand controller if something is blown.

Good luck.

Hand control comes up with no response 16


bintangchris: error 16 indicates a bad Hand controller, you may need to buy another one, also check all your connections going to the head assembly.Also error 16/17 indicates the HC cant communicate with the the RA/DEC control boards. It may need to go back to Celestron for repair.

Actually, its NOT about an LX90, but rather my Meade LX6 10", f/6.3 scope...whos hand controller is displaying error messages from the encoders on power up. Can you help me? Great scooe, recent...


The motors have encoder wheels, that pulse when the motor turns, to tell the computer that everything is OK, and to indicate its position. If the wheel is loose on the shaft, then errors are indicated. A second point of error, is dirt in the wheel slots that disturb the sensing, or the optical pickup is bad.
